Release 12.0.0 alpha 0 This release does not contain most of the changes planned for the 12.0 release, but it does have a few incompatible changes that necessitate a version bump. Since ChefDK's appbundler feature doesn't support git-installed gems and the chef-dk library relies on some fixes in the Chef 12 code base, we are making a very early rubygems-only prerelease.
